I have UC and have been in remission for about four months. Over the last four weeks, my joints (knees, ankles) have been starting to ache/swell again and my eyes are super sensitive to sunlight. I have been going to the toilet more often and having a lot of mucous, terrible gas, cramping and abdo pain that wakes me in the night. However, I have no blood. In my last two flares, I always had blood. I feel stupid ringing the IBD nurse if its a false alarm. Does this sound like I could be at the start of an impending flare up? I'm currently taking 8 Asacol a day and 150mg of Imuran.
